I use the "preGenerateCommands" and "dependencies" like this:

     "configurations" : [
         {
             "comment"             : "Classic app.",
             "name"                : "eqapp",
             "preGenerateCommands" : ["sed -e 
's#topdir/#$PACKAGE_DIR#' src/config/constants.d.in > 
src/config/constants.d"],
             "dependencies"        : {":dgtalib" : "*", 
"gtk-d:gtkd": "~>3.3.0"},
         },
       ....

Hope this helps you.
